WebJan 17, 2024 · So we find: 81x4 −625 = (9x2)2 −252. 81x4 −625 = (9x2 −25)(9x2 +25) 81x4 −625 = ((3x)2 − 52)(9x2 + 25) 81x4 −625 = (3x − 5)(3x + 5)(9x2 +25) The remaining quadratic factor is irreducible over the reals. That is, it cannot be factorised into linear factors with real coefficients. Answer link. WebSolve your math problems using our free math solver with step-by-step solutions.
